ABSTRACT:
The invention relates to a test apparatus (1) with an end face (11) in front of which a yarn, roving or sliver is moved along in the longitudinal direction in order to test properties, with a plurality of zones of action (8, 9, 10) for producing a respective interaction between the test apparatus and the test material. In order to be able to provide a simple path, which is independent of the number of zones of action, for the yarn, roving or sliver, the yarn, roving or sliver is guided at least approximately in one plane transverse to the end face.
